I don't feel like I can really answer this because I'm so troubled by the ethics of banning travel. Ethically speaking, by banning travel we are saying to people "you might be infected and so we think you should just stay where you are and die". However having said that, I think that quarantine is essential at this point, and I'm not entirely sure why we haven't set it up! I think quarantine is good for two reasons, firstly if you ARE effected by ebola, you are in an institution that is equipped to recognise it early and hopefully give you the best odds of survival, and obviously for the wider community it's best that it's contained.

As for flight bans, there just aren't any simple answers I don't think because you could walk into a neighbouring country with your dormant ebola virus, hop on a plane, and be in Australia 20hrs later, with no one any the wiser. At least with flights operating in and out of effected areas we can track where people are coming and going from more easily.

Definitely. Ebola is a very deadly disease that is very contagious and has a high mortality rate. Its also very hard to treat.Vaccination is in the infancy stage.I can imagine this disease wiping out the population of a small country. The problem can be better tackled if it is confined to one geographical location.
